. I I v v I To alil ihh o m z' t may concern .1 a Be it known that I, JOHN ALLEN HEA Y,

- a citizen of the United States,'-and a resident 'ashington, in theDistrict of Columbia, nyented certain new and useful Imements inSelf-Starting Internal-Com prov bustioniEngines, of which the followingis afull and clear specification, reference being had to theaccompanying drawings, in wh1ch Figure l is a side'elevation partlybroken away;, Fig. 2isavertical section; and, Figs;

; 3, 4 and 5;are detail transverse sections of the manually controlledvalve device.

The object of this invention is toso construct the starting mechanismthat it shall be built into the engine proper, thereby doing away withthe unsightliness, unreliability, lack of durability, and liability toderangement which are necessarily incident to those starting mechanismswhich are mere attachments to an engine.-

the pitmen connecting the pistons to" the main crank-shaft d, allconstructed in substantially the usual manner.-

diameter than themain piston and working I in a supplemental cylinder fformed as a dapted to be reciprocated by means of a .'cated near theupper extremity .of the sup-- continuation of the main cylinder, Working between each supplemental piston and its cylinder is a valve-sleeveg WlllCll 1s valve-rod h connected to an eccentric 2' on thecrank-shaft.

Each valve-sleeve is provided at dia- .metrically opposite points withports j and 7c and these ports are adapted to register respectively withcylinder ports Z and m loplemental cylinder. The ports Z are all locatedonthesame side of the cyllnders and 'they all communicate wit-ha pipeormanifold-"m'whileiports'mare all on the opposite sides of thecylinders of the engine and are all in constant communication with asimilar pipe or manifold o.- i

The pipes n and 0 are at their ends con- Specification of LettersPatent. Application filed April 5, 1912. Serial no. 688,634.

which is connected by means of It will be observed thaflwhile the engineis running under fuel power, the valve-q case the supplemental pistonswill act as air pumps, drawing air in through port 8, pipe isandexpelling theair 1 0, ports m, and'ports through-{ports a nd-Z,"pipesn and t, and

thence into the storage tank a. lVhen the the tank is 'obtai'ned,-

'will be adjusted as shown in Fig. 3, in which a I tank, thus nullifyingthe pumping action.

The engine Will then continue to run against the pressure of the airwhich is entrapped in the supplemental cylinders and the connect edports and pipes, and thislentrapping of the air-in the cylinders servesto cushion the upward 'strokes of the working. pistons,

decreasing the Wear and thereby materially noise of the operation of theengine.

lVith the desired pressure in the tank, to start the engine. it issimply necessary to turn the valve. plug in Fig, 5 in which position thepipe n will be open to the atmosphere and the pipe 0 will be placed incommunication with the I tank through the pipe 5, whereupon the comepressed air will be admitted to that cylinder or cylinders whose portsis are in register with ports m. This will cause the supplementalpistons and cylinders to act asa mog to theposition shown tor instarting the engine. Of course it will be understood that the cylinderarrangement of the engine and'the'arrangementof ports is andm will besuch'that-at all times there will be at least one pair of ports is and'min register; in the twin-cylinder type of fourcycle engine I haveshown'there will at all times be at least two pairs of ports is and 'min register so that. 'upon the admission of. compressed air into pipe 0there will be at least two supplemental pistons available as .motorpistons, thus assuring an effective starting of-theengine under the-mostadversefconditions.

'It will be further observed that thervalve -'or controlling means maybe greatlyvaried without departing from'the spirit of my inventlon; Initsbroad aspects, my invention contemplatesthe employment between "thework piston and the crankeshaft of a'supiplemental piston of a largerdiameter than the 'work piston, together with automatic or as a' motorpiston, suitvidedfor manually bringingabout the conversion; and asuitable storage tank for the compressed air-being provided. .a 1"Having thus -r-ul1 described my invention,-
